The content of metal elements such as calcium, iron, potassium, magnesium and zinc in food is high, which eventually produces alkaline substances after decomposition and metabolism in the body. This food is called alkaline food (or food or alkaline food). Common alkaline foods are: vegetables, fruits, beans and their products, almonds, coconuts, tea and so on.
Under normal circumstances, the pH value of human blood is maintained between 7.35 and 7.45 due to its own buffer adjustment. After eating an appropriate amount of acidic or alkaline food, nonmetallic elements in food are oxidized in the body to generate anionic acid radicals, which are combined with ammonia in the kidney to generate synthetic ammonia salts and excreted. The metal elements in it are oxidized in the body to form cationic basic oxides, which combine with carbon dioxide to form various carbonates and are discharged from urine. This still keeps the pH value of human blood within the normal range, and meets the requirements of physiological acid-base balance.
If the blood pH value deviates from the normal range due to improper collocation of various foods in the diet, especially when the intake of acidic foods exceeds that of alkaline foods, it is easy to cause physiological acid-base imbalance, which is acid-base imbalance.
In three meals a day in our daily diet, under normal circumstances, acidic food often exceeds the required amount (because most people's staple food belongs to alkaline food), leading to acidic blood. In this way, it will not only increase the consumption of basic elements such as calcium, magnesium and iron, but also cause calcium deficiency or anemia in human body, deepen blood color and increase viscosity, and also cause various acidosis. Children with acidosis are prone to dermatosis, neurasthenia, fatigue, hyperacidity, constipation, dental caries, rickets and so on. Acidosis mostly occurs in middle-aged and elderly people, who are prone to neuralgia, hypertension, arteriosclerosis, gastric ulcer, cerebral hemorrhage, cancer and other diseases. This so-called "acid-base imbalance, all diseases are in the body"!
1. Nutrients such as carbohydrates, protein and fat that acidic foods enter the body are acidic substances, such as pork, beef, chicken, fish, shrimp, egg yolk, rice, barley, wheat, brown rice, laver and persimmon. These foods constantly produce acidic substances in the process of metabolism, but they are neutralized by buffering substances in the blood, so as not to make the internal environment of the human body acidic. At the same time, the body excretes a lot of acidic substances every day to maintain the acid-base balance in the body.
2. There are few alkaline substances in the metabolites of alkaline food, which mainly come from food, such as milk, egg white, soybean, adzuki bean, tofu, spinach, cucumber, eggplant, carrot, lotus root, onion, sweet potato, potato, kelp, grape, banana, apple, orange, pear, watermelon, garlic, tea and other alkaline foods. They are oxidized and decomposed into inorganic salts and gases in the body. Inorganic salts are soluble substances, that is, alkaline substances, which can neutralize acidic substances and maintain the normal acid-base balance of human body fluids.
The human body has the ability to naturally regulate the acid-base balance of body fluids. Therefore, in general, when you are partial to meat (acidic) or vegetables and fruits (alkaline), don't worry too much. Regulating acid-base balance mainly has the following links; 1。 Regulation of respiratory center. Once the acidity and alkalinity of body fluids increase, breathing will be accelerated and more carbon dioxide will be exhaled. 2. Renal excretion. When the body fluid is acidic, acidic urine can be excreted from the stool through the kidney. Neutralization of liver. The liver produces ammonia in the process of protein metabolism, and when there is excess acid in the body, the blood vessels dilate; When alkaline, blood vessels contract, thus making acid-base neutralization neutral.
Yifeng alkaline life liquid is superior to tap water and purified water in physiological efficacy, because Yifeng alkaline life liquid presents many water quality characteristics. The main points are as follows:
Acidic food: pork, beef, chicken, egg yolk, carp, oyster, dried squid, shrimp, rice, brown rice, wheat flour, bread, peanut barley, beer, etc.
The rice, noodles, all kinds of meat, eggs, fish and shrimp we eat every day come from animals. They contain nonmetallic elements such as phosphorus, sulfur and chlorine, which are oxidized in human body to generate a large number of acidic substances. These foods are the source of acidic substances in the body.
Alkaline food: soybean, bean curd, kidney bean, spinach, lettuce, radish, carrot, potato, lotus root, onion, pumpkin, cucumber, kelp, watermelon, banana, pear, apple, strawberry, persimmon, milk, tea and so on.
These foods are mainly all kinds of vegetables and fruits, which are rich in metal elements such as calcium, magnesium, sodium and potassium, and produce alkaline substances during metabolism in the body. Although fruit contains organic acids, it tastes acidic, but the final product of oxidation in the body is alkaline, so it also belongs to alkaline food.
